I just bought the Wahoo Kickr Core wheel off trainer and I'm going to need a cassette to put on it. It comes with a Shimano freehub and I don't believe there is a conversion hub yet for Campy. What Shimano system gives the closest approximation of Campy 10? I know it won't be perfect, and I'm not looking to modify the drivetrain with a shiftmate or anything else. Is there a Shimano splined but campy spaced cassette available? I know there used to be, but it didn't work well as the position still wasn't right so you had to mess with the limit screws.

When my bike was still relatively new I put a Shimano 10 wheel on it and did a long ride, and came home and swore I'd never do that again. Shifting basically sucked. Even though it was a better wheel I gave up trying and ultimately bought a similar wheel with Campy.

So, is Shimano 10 as close as I'll get? Or is there something from Miche? or SRAM, or Shimano 9? Shimano 11? or will I need a different chain? It is an indoor trainer, ERG mode so I don't have to shift a lot, but it does need to work OK.

I love my Campy gear but I wish it were a little more compatible with everything else. As I look around I keep reading the 11 speed is pretty much the same across all the systems but not the 10.
